' AIR-INTAKE REGULATOR.

Specification of Letters Patent Patented July 2 191 8.

Application filed September 20, 1916.. Serial-No. 121,271.

To all whom it may concern:

Be it known that I, EDMUND J. PRICE, a citizen of the United. States,residing at Montague, in the county of Siskiyou and State of California,have invented certain new and useful Improvements in Air-IntakeRegulators, of which the following is a specification.

This invention relates to a device forregulating the intake of air tothe mixing chamber of a gasolene motor.

The primary object of the invention is to provide a regulator of thischaracter disposed in the manifold of the motor whereby may be obtainedfor regulating the gas mixer before it passes into the motor.

The above and additional objects are accomplished by such means as areillustrated in the preferred embodiment and'in the accompanyingdrawings, wherein like characters denote like or corresponding partsthroughout the several views, in which;

Figure l is a perspective View of the device showing the same attachedto the manifold.

Fig. 2 is a transverse section through the device. V

Fig. 3 is a section on the line 3+3 of Fig. 2, looking in the directionindicated by the arrow.

Referring to the drawing, wherein is illus' trated the preferred form ofmy invention, and in which like numerals of reference indicatecorresponding parts throughout the several views, the manifold pipe 1 isof the usual construction and is adapted to take the air into the mixingchamber for mixing with the gas for providing a proper mixture for themotor.

The present improvementcomprises a cylindrical chamber 3 with anintegrally formed stem 4 having screw threads whereby the stem may bescrew threadedly mounted in an opening 5 formed in the manifold 1. Thestem 4 is hollow and thereby establishes communication between theinterior of the cylindrical chamber 2 and the manifold pipe 1. The openend of the chamber 2 is provided with exterior screw threads forreceiving the interior screw threads of a cap 6. The cap 6 is providedwith a plurality of circumferentially spaced apertures 7 whichcommunicate with the interior of the chamber 2. For

2 provided on itsend wall 2 opening and closingthe opening 7 I provide avalve 8 comprising a stud 9 depending centrally into the chamber 2 and acircular flange 10 is integrally formed with the stud and is in contactwith the interior of the cover 6. An integrally formed stem 12 extendsthrough a central opening in the cover and receives an operating lever13 having connection with a handle it which may be reciprocated foropening and closing the valve. Interposed between the closed wall of thechamber 2 and the valve flange 10 is a coil compression spring 15 whichsurrounds the stud 9. This coil spring holds the valvefiange 1O tightlyin engagement with the cover 6 and thereby prevents the air from passingaround the edge of the flange and through any one of the openings Asegmental slot 16 is provided in the flange 10 and, when the valve is inopen position, this slot communicates with the openings 7 and therebyestablishes communica tion between the interior of the chamber 2 andtheexterior thereof. When the valve is in this position a maximumquantity of air will rush through the openings and into the air chamber2 and will then pass through into the manifold ipe l and thus onward tothe mixing cham er.

From the foregoing it will be observed that a very simple and durablemixer has been provided, the details of which embody the preferred form.I desire it to be understood however, minor details of construction maybe made without departing from the spirit of the invention or the scopeof the claim hereunto appended. I

I claim:

A device of the character described comprising an'air chamber having oneend provided with a stem havinga hollow interior communicating with theinterior of the chamber, a cap mounted onthe opposite end of thechamber, and provided with a central circular'opening, and a pluralityof circumferentially spaced openings, a valve element including a stemextending through the central opening in the cap, the said stem carryinga relatively large disk disposed within the chamber and in close contactwith the inner face of'the cap, the said flange having dependingtherefrom a stud, a coil compress1on springembracing the stud and interposed between the disk and the end of the that slight changes in the isaidchamber for normally maintaining the disk in close Contact with thecap, .thesaid disk having a segmental slotequal inlength to the distancebetween the end openings in the said series of circumferentially spacedopenings in the cap, and a lever attachedto the sten ofgthe said valveelement.

In testimony whereof I afliX my signature in presence of two witnesses.

EDMUND J. PRICE.
